| 摘要: |
| 局部干法水下焊接以其相对经济、灵活的优势,逐渐成为水下焊接中的主要方法之一.研制了局部干法自动水下焊接试验系统,在此基础上利用汉诺威弧焊质量分析仪对包括空气中、5 m水深和15 m水深三种焊接环境下的焊接电参数进行了采集和分析.结果表明,水下焊接试验系统能够实现局部干法自动水下焊接,焊接过程中的熔滴过渡形态与焊接环境有关,为科学评价局部干法自动水下焊接时的焊接工艺以及焊接质量控制提供了试验依据。 |

| Abstract: |
| Local dry underwater welding is one of the important techniques for its economy and flexibleness.Based on the development of local dry automatic underwater welding system, the electrical parameters of welding in air 、5 meters and 15 meters under water are obtained and analyzed by using HANNOVER analysator.The results show that the welding test system can carry out local dry automatic underwater welding successfully and the metal transfer mode during underwater welding is relate to welding environment, which provide experimental foardation for analysing and assessing welding procedure and welding quality of local dry automatic underwater welding. |
